I do not know anything about technical jargon or anything about add-ons or plug-ins, I just know that typically if I open a PDF file from a website it opens just fine in the browser. However, I am unable to open PDFs inside of Adobe Reader. When I do, the error message reads as follows:

"Adobe Reader cannot show documents in this browser. We are sorry, but Adobe Reader is unable to show documents in this browser configuration. Please use your browser to download this file and open it in Adobe Reader or Adobe Acrobat. To avoid this message in the future, many browsers provide a way to turn off certain add-ons, and some are able to show this document natively. Please contact your browser vendor for more details."

I have no idea how to fix this, as Adobe Reader is installed and I assume it is installed correctly? Please, any help would be fantastic.

Opening the "Add-ons Manager" shows a message "You don't have any add-ons of this type installed" despite the fact I have many add-ons installed. In fact, I can still use add-ons just fine, they just don't show up in the manager. So, I can't access preferences for most of my add-ons.

I had this problem once before and was able to solve it through extensive Google searching. However, when I fixed the problem before, I had to re-add all of my add-ons to the browser window as it was reset to the default in fixing it. My issue isn't so much how to fix it like I did before, but rather—since it seems to have been only a temporary fix—figure out how to prevent it from happening again. See, I really don't want to have to do what I did before as it is time consuming. Especially, if it's going to happen again. Like, I don't want to have to reset and re-organize Firefox every couple of months.

The solution I used before, if I recall correctly, was deleting some preference files, re-opening Firefox, and then putting everything back the way it was. Restarting Firefox in safe mode did nothing and restarting my computer did nothing. I can't remember if I updated Firefox after noticing the problem the first time; I don't think I did, so I'm not sure if it would've fixed the problem or not (or if updating caused it because I had recently updated Firefox prior to noticing the problem).

One more piece of info is that the first time this happened to me was Firefox 14 or 14.1 (or .0.1 maybe).

Hello. I have 2 different animated gifs on the site I'm building with Weebly. One of them is a loop which works just fine. The other gif is made to just happen once. However, it will not replay when its page is refreshed or revisited (it does replay on other browsers). So I'm wondering what can be done to fix this.

I have been using yahoo mail on firefox for years, but now I can't reply to an email. Every time I try to reply to a message I get this:

Yahoo! Mail found the original email, but encountered problems displaying it. Please try again later.

I have switched browsers, and both explorer and chrome work fine. So, I will be switching permanently to Chrome if this cannot be fixed soon. I really like Firefox, but if I can't reply to an email, what good is it to use Firefox when I can reply fine on other browsers?

I've added a few Firefox add-ons since upgrading to Firefox 16.0.2 and would like to donate. However, the donate links which re-direct to paypal are not working for me (the donate links that redirect to the developers personal website do work, however). After trying to re-direct to paypal, it doesn't succeed and then turns the webpage a transparent grey, with the Firefox webpage visible underneath. Before upgrading to Firefox 16x, I was running Firefox 8x with Flash Player 10x (with Windows XP sp3), and the donate link worked fine. It should be noted that I am running Flash Player 10.3x because I also have the Real Player Download plug-in which is incompatible with Flash Player 11x. I've disabled other add-ons which might be causing a conflict (like Adblock plus and Real Player Download), and have enabled pop-up windows in Firefox options, but the donate link still doesn't work. I think my only option is to upgrade Flash Player 11x (which then I would have to downgrade after donating if I want the Real Player Download plug-in to work). Anyone else experiencing this problem?

I am using a macro to fill in a form and select fields in the form. The fields are titled and i want to use the field title to select the field and thus need to copy the name to compare with the search text and tab to the next requested field.

Until recently I have accessed my Easyjet account with no difficulty. My son has used my laptop in the past to print out his boarding pass. No problem in the past. For a week each time I went on to the Easyjet web site to make a booking it kept throwing me onto my son's account and even with his password to log out it just kept returning me to his account. I tried a different laptop and found that I was being connected to my son's partner's Easyjet account.

I contacted Easyjet but the solutions they offered were already ones I tried.  I then went to an Apple store and as the adviser was not familiar with Firefox she suggested using Safari which I did and then I was able to make my booking through my Easyjet account.

I have ask.com as a search engine. I tried deleting by uninstalling it but it is still there although uninstalled. I have uninstalled Firefox butt it comes back when I reload it. I am asking this question as a last resort as if I can't get rid of it I will start using Safari for my internet

I'm trying to play an audio clip on a website. The site shows that the clip is playing, but I have no sound. My speakers are on and none of my volume mixers are muted. I played a clip from a different website and had sound. I spoke with Customer Service for the website where I'm not getting sound, and they tried playing the same clip on their computer, using Firefox, and it played the sound. I also tried playing a different clip on the same website, but again didn't have sound.

I'm using Firefox 16.0.2 on Windows XP

I have Firefox 16.0.1, and as of lately, it's become too unbearably slow for me to continue using it. Even when typing this message, at certain points it will lag. When switching to new tabs or clicking links, it lags HORRIBLY. At least 4-5 seconds of wait time. And now it's started to screw up my enjoyment of YouTube videos by lagging when scrolling down the page (as it does with other sites) and lagging the video itself. I've tried the reset feature. That did absolutely nothing for me.

The only add-ons that I have are AdBlock Plus 2.1.2 and the FTDeepDark 4.8.3 theme. And I've already tried disabling (even removing) them to no avail.

What must I do for Firefox to run properly and quickly? I've been a huge fan up until now, and I'm seriously fed up with it. I have a very quick laptop (Win7, i7920XM, 8 gigs of DDR3, 256GB SSD, dual 5870 GPUs, etc.), and Firefox has always run great up until the past few month.s

This is for anyone who has had issues loading Facebook, eBay, twitter or any other site which shows plain text pushed to the left hand-side of the screen and fails to load images.

This issue had me stumped for about 3 hours. No matter what I did. No matter what I disabled. The problem remained. I cleared my cache, reset cookies, disabled addons, reset Firefox to default settings and kicked my pc a few times for good measure.

The problem was fairly simple and at my end, this is not a problem with firefox. SSL certification for facebook was being deemed invalid and therefore the site failed to load properly. Now because Firefox doesn't deal with SSL certificate failures, there had to be something else going on in another program. I then realised that Kaspersky Internet Security 2013 was the problem. If a website failed SSL certification for any reason Kaspersky Blocks access to the site which was causing the page to not load properly. You have to disable Kaspersky's SSL certifcation checks to be able to run the websites properly. You need to load your Kaspersky main menu and click Settings once there go to the tab that looks like a cardboard box (Object Detection Settings and Exclusion Rules) then when you can see a list of different options select Network and you should see Monitored Ports and Encrypted Connections Scan, disabled the encrypted connections then reload Firefox and try the webpage that wouldn't load. To know that kaspersky is the problem, you will get a dialogue saying you have to add facebook as an exception since it failed SSL Certification and this was the culprit for me atleast.

I looked at the mozilla support forums and it seemed to me, many people were getting this issue and some issues went completely unresolved and there was no mention about Kaspersky, so I hope this helps.bold text

I use my laptop both at home and at work. And in each venue I use a different user log on. But I wish to have firefox use the same profile for each user log on. How can I get firefox to point to the same profile for each user?

A little while after I start going through my e-mail the Checking button starts going and won't stop and if I re-load the page all the e-mails I have either read or deleted come back on all over again! I would appreciate any help you can give me and THANK YOU in advance!

Several keywords on my site have suddenly developed "links" to affiliate ads. This only appears on Firefox browser though. No sign on it on Explorer or Chrome.

There is no visible script or coding that I can find.

Any ideas.
